RE: Package marking for MPC555

Randy,
 
 
Thank you for your help!
 
Is there a Colossus type decoding machine for this kind of information, or is this secret? ;-)
 
Best regards.
 
 
Jean-Christophe

the letters prior to the 4 digit date indicate where the device was
assembled (location) and provide a trace code back to the wafer lot used
to assemble the device.
